The rate constant for a first order reaction is 0.060s-1. when the temperature is increased from 298K to 331 K , the rate constant increases to 0.18s-1. Calculate the activation energy for this reaction. Use kJ/mol for the units. The activation energy in kJ/mol equals (include the units in your answer):
